Description

I suggest to look at the diagram. A picture is worth a thousand words. diagram

Tables

tablename description

Views

view name descpription
book_adder adding book here cares about existence of authors and publishers
books_rank shows ranking of books with average rate and amount of sold copies

Additional info

There are triggers validating e.g. ISBNs correctness (database can handle both ISBN-10 and ISBN-13), polish 9-digit phone numbers and polish NIP (VAT identification number). Customer has to have a book bought in order to rate it. Multiple rating of same book by same user updates resulting one. Removing customer from database makes all his data deleted (orders, ratings and related). If adding of a book with book_adder fails its publisher and author won't be added to database.
